Expert has over 25 years experience in environmental chemistry and engineering. He conducted research on water pollutants (agriculture chemicals, biosolids, heavy metals) in academia and governmental institutes in Poland and Canada. He later applied his knowledge and experience in environmental engineering company to design water and wastewater treatment processes for various industries (chemical, electronic, automotive, steel, food processing, cement, mining, pulp and paper) using various chemical and biological technologies and advanced oxidation processes (AOP). He also conducted evaluation of many industrial and municipal treatment plants using aerobic and anaerobic respirometry and prepared guidelines for improvement of their operation.
He is familiar with most analytical techniques including traditional wet chemistry (eg.COD, BOD, TKN, TSS, TDS), UV/VIS, ICP and IR spectroscopies, GC/MS, HPLC, Ion Selective Electrodes as well as with water and wastewater on-line quality monitoring equipment. He also conducted advanced validation and interpretation of analytical data in relation to specific environmental conditions.
Expert has been involved in several projects related to environmental sustainability including evaluation of cement manufacturing, leachate treatment, waste management and pesticide formulation.
He provided scientific and technical support for legal firm in environmental litigations related to petroleum products spills, discharges of toxic chemicals into natural waters and heavy metals contamination of water and soil.

Evaluation of third party report on treatability studies on groundwater from former gas plant site, including:
- applied methodology
- analytical data
- site specific applicabilityEvaluation of sources of storm water contamination at gypsum board manufacturer and proposed solution.
He prepared a sampling program for chemical and biological parameters.
Based on analytical data main sources of chemical and biological contamination were identified.
Storm sewer cleaning and modification of gypsum transportations were proposed.Evaluation of scaling problems in municipal water supply system..
He reviewed the existing analytical data and observations.
He prepared sampling program and supervised its implementation.
He designed a treatability study using selected sequestering agent to determine the optimum dose of the chemical.
He prepared the schematics of chemical dosing system and analytical program to evaluate its efficiency Identification of the source of petroleum hydrocarbons spill based on PAHs ratio.
Two potential sources of contamination were considered:
-diesel oil storage facility
- crude oil pipeline
Extensive soil sampling and analytical program was prepared and implemented.
He proposed an application of specific PAHs ratio (chrysene/phenantrene) which is substantially different in diesel oil and crude oil to identify the source of pollution. Using the proposed method the crude oil pipeline was found the source of hydrocarbon spills. Evaluation of internal drainage scaling under the building
Despite internal drainage under the building a client noticed seepage of groundwater in the basement.
Analyses of groundwater indicated significant decrease in concentration of calcium in the drainage system as compared to the groundwater related to scaling in the drainage pipes. Camera inspection of the drainage system confirmed this.
To mitigate the problem pressure cleaning and modifications of the drainage system were proposed and implemented.Evaluation of Mercury Emission from Biosolids Application in Canada
The project involved the following activities:
i) Collection of data from all Canadian provinces regarding:
- amount of biosolids applied into the agriculture land
- concentration of mercury in biosolids
- guidelines regarding biosolids application (Hg limits, how often applied)
- speciation of Hg (if available)
ii) Literature review about mercury fate in the soil environment, particularly emission
at different climate conditions
iii) Review of field data about mercury concentration in the air recorded by
Environment Canada monitoring stations
iv) Model development for mercury emission from soil at different climate conditions
v) Application of the model for calculation of mercury emission in Canada
Leachate treatment plant at large municipal landfill
The leachate contained high concentration of organic substances, heavy metals and ammonia. Respirometric tests indicated the presence of nitrification inhibitors.
Pilot studies revealed that removal of nitrification inhibitors and heavy metals can be achieved together with substantial reduction of ammonia by struvite precipitation and aeration. Treatment process included:
- Chemical pretreatment to reduce organic and ammonia load as well as nitrification inhibitors by phosphoric acid addition and aeration
- Two stage biological treatment for organics removal followed by nitrification/dinitrification
- Ozonation of biological effluent for disinfection and color removal
Troubleshooting Services for Municipal wastewater treatment plant receiving industrial wastewaters:
Treatment plant experienced upsets of biological treatment related to industrial wastewater discharges into the sewer system. Troubleshooting services included:
o Respirometric tests on wastewater streams
o Extensive sampling and analytical program
o Selecting industrial wastewater stream for pre-treatment
o Selecting and installing on-line monitoring sensors
Troubleshooting Services for zero discharge wastewater treatment plant
The plant treated leachate and groundwater contaminated with organic substances, ammonia, and heavy metals using membrane biological reactors (MBR) followed by reverse osmosis (RO). RO reject stream was treated using chemical precipitation, an evaporator (MVR) and mineral slurry dryer.
The plant experienced extensive scaling in the evaporator and was not able to conduct denitrification.
Troubleshooting services included:
o Evaluation of analytical data from the treatment system
o Evaluation of analytical data for scale deposits
o Review of design manual and plant schematics
o Evaluation of calcium concentration versus calcium salts solubility at various stage of treatment
o Recommended modifications to the treatment process, particularly RO reject stream
o Recommended modifications to the MBR operations based on dissolved oxygen (DO) and oxidation/reduction potential (ORP) data to allow for denitrification to be completed
o Selection of chemicals for evaporator deposits removal
